ABS light, 1130 and 1132 codes

[pablocullen]

Hi

Ive got the j10 1.5 DCi model and im seeing some super weird stuff.

Sold the car last week with the proviso i sorted the bits on the MOT, lower suspension arm bust and an anti-roll bar.

Did the work over the weekend, took it for a drive and got both traction control lights on the dash, oh dear.

Assumed i had bonked an ABS sensor so bought a cheapo one on amazon next day but they read 0pm (came in a pack of 2) so it then throws an ABS light.

I have the 1130 and 1132 codes which usually is that exhaust pipe that you have to clean. I went ahead and took the pipe off to fully inspect it, its perfectly clean so ive fitted a new set of glow plugs and an exhaust sensor, codes remain (im thinking it needs to regen?)

I have today bought a Bosch wheel speed sensor from Euros and its thrown the ABS light again, heres where it gets weird, take a look at the graphed output. What on earth could be causing that? Ive not touched the ring, not had the hub apart, i drilled out the old sensor and replaced with the now 3rd one. Ive cleaned the connectors with isopropyl alcohol and a toothbrush.

The sensor thats reporting the error is the same one showing the dips on the graph.

Any tips are extremely welcome, im at my wits end as i need the car gone but want to do right by the new owner.
